question.... if i use two brands of sunscreen with SPF 15 each, does that make it liable to be at least SPF 30?
haha im not sure about that. but even if they do add up, you shouldnt expect it to really be SPF 30. business ploy and corporate greed. and if a product is said to be water resistant you should reapply every forty minutes when you're in the water.fully water resistant, reapply every 2 hours.
